BURNER.

Specification of Letters Patent.

Patented Apr. 4, 1916.-

Application filed December 16, 1915. Serial No. 67,241.

To all whom it may concern:

Be it known that we, JAMES PRICE and ALVAH W. BROWN, citizens of the United States of America, residing at Grand Rapids, in the county of Kent and State of .Michigan, have invented certain new and useful Improvements in Burners; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to burners and while of especial value when used in connection with fumigating apparatus, it is of course understood that the burner may be used in many other relations. 7 7

It is the object and purpose of our invention to provide a burner in which a solid fuel such as paraffin or the like may be used and in which, by virtue of the novel construction of the burner, a complete combustion of the fuel may be had, the flame produced being of a bluish character Without the presence of color indicating the presence of particles of carbon and incomand 4 are sections taken on the lines 33 plete combustion thereof.

A further object of the invention consists in the provision of a construction with readily separable parts for the introduction of fuel into the burner and of a receptacle to be used in connection with the burner which is easily detached therefrom or which may be replaced by a similar receptacle containing material to be vaporized by the burner.

Various other objects and purposes other than those specifically enumerated will also appear as understanding is had of the construction which embodies our invention disclosed in the accompanying drawing, in -which;

Figure 1 is a side elevation of the burner with all parts assembled and in place. Fig. 2 is a vertical section taken through the construction shown in Fig. 1; and Figs. 3

In the construction of the burner a shelllocated. Member'3 is in the shape of a shal low inverted cup and at its central point has a portion cut away to form a circular opening 4:. Atashort distance from the edges of opening 4 a plurality of small openings 5 are formed and immediately below the lower edges of member 3 a row of openings 6 are made in the shell 1. The shell thus described is adapted to be detachably connected with a fuel holding: standard comprised of a plate 7 of sheet metal from which project downwardly extending legs 8, four in number being indicated in the present construction. Each leg is formed with a bead 9 against which the lower edges of the shell 1 engage so that the shell passes over the upper part of the standard and is stopped by the beads I in such position that the row of openings 6 is directly abovethe plate 7. The central portion of the plate is removed and in the opening formed a shallow cup 10 is fixed which is adapted to receive the fuel. In the operation of theburner a wick 11 of conical form is used which is adapted to be forced over a sheet metal member 12 having its ends bent angularly as indicated at 13 so that it will stand upright and hold the wick in proper position directly below theopening 1 in the member 3.

A receptacle 14: formed of sheet metal is detachably positioned in the upper end of the shell 1 being formed with a bead 15 which limits the distance that the receptacle 14 may be inserted in the shell. the bottom of this receptacle coming immediately above the upper row of openings 2 inthe shell. Adiacent its upper end receptacle 14 is made smaller in diameter and terminates in a screw threaded neck 16 towhich a screw threaded cap 17 may be secured.

It is apparentof course that various types are found in miners lamps and the like. 7 However, the plurality of openings 2 will of receptacles may be used with this burner but a receptacle of the form described has been found most efiicient when the device is used for fumigating purposes, the fumigatingmaterial being contained by the receptacle and the cap being removed when a room is to be fumigated. U

Vvhen the'parts of the burnerare assembled and with fuel in the cup 10 which,

preferably, is of paraflin, the wick may" be lighted and for a short time a yel-, lowish flame will be produced but after the device has become warmedqair. passing through the openings 6 to the wick and through the openings, 5 to a point above the also permit the entrance of air from the outside so that, this air will aid inthe combustion of the fuel.

'W'ith a burner of this character it has been found that a definite quantity of fumigating material may be vaporized in the receptacle in a time practically one-third of that heretofore required to vaporize the same amount of material with other burners now on the market and this without danger of fire from the burner.

We claim 1. In combination, a cylindrical shell open at both ends and provided with a plurality of rows of openings situated at a distance from the ends of the shell and with a single row of openings located a distance from said plurality of rows, an inverted cup-like member having a large central opening and a plurality of small openings adjacent and sur-.

rounding said large opening secured in the shell between the single row and the plurality of rows of openings, a receptacle positioned in one end of the shell and detachable therefrom, the bottom of said receptacle lying in a plane substantially coincident with an upper row of the plurality of rows of openings, a fuel holding standard detachably positioned in the opposite endof the shell havingits upper surface in a plane slightly below that of the single row of openings, legs to said standard,beads on the legs limiting the insertion of the standard into the shell, and a cup for containing fuel secured centrally on the standard.

2.111 combination, a shell open at both ends and provided with a plurality of openings at a distance from the ends of the shell,

and with a single row of openings located between said plurality of, openingsand the lower end of the shell, a member secured within and extending across the shell, said member being provided with a compares tivelylarge centralopemng and 'WIth a plurality of smaller openings adjacent and around the larger opening, said member lying between the single row of openings and the plurality of openings in the shell,- a re 'ceptacle removably inserted in the upper end of the shell, a fuel holding device removably inserted in the lower end ofsa'idshell and means: to limitthe insertion of said :recepe tacle and device into the shell.

8. In combination, a shellhaving a member secured within and across-itat a distance. above the lower .endofthe shell, saidishelll having a plurality of openings inthe sides thereof above said member anda zsingle row of openings below 1t andxsaid-member, having a comparatively large opening in ,the-

center thereof. with .a plurality of smaller; openings around and adjacent said large;

opening, a receptacle removably inserted :in

the. upper; end of the shell and a fuel holding member-removably inserted in the lower end of the shell adapted to contain a wick 110- cated below the larger-central openingin:

said member.. V V V 4. In combinatiomashelha member LS8 cured within and acrossthe-shell between. the ends thereof, said shel-libeing provided with openings in its sidesabove andbelow the memberto permit the entrance of air,

and said member having a-large; central opening wlth auxiliary smalleropenings ad-- jacent the large opening, a receptacle in? sorted in the upper end of theshelhabead on the receptacle :to limit the: inward movement of said receptacle, a fuel holder; having a plurality of depending legs inserted in the. lower-endiof the shellzand beads on said'legs to stop the inward movement :of said fuel holder, into the shell.

5. In combinatioma shell having .a mem-' ber secured within. and across :it a distance" above the lower end thereof, said'shellfbeing provided with openings in its sides above andbelow the member to, permit the-zentrance' of air, and said member having a com tral opening, a receptacle removably insert-c ed in the upper end of the shell, a fuel; hold: ing member removably inserted inthe lower end of the-she'll anda wick locatedin the fuel of said fuel holdingmember below the:
